Harm of perm In the process of perm, the scales on the hair surface will be destroyed. Leaving the internal structure of hair unprotected will lead to the loss of internal moisture and nutrients, which is harmful to hair, scalp and hair follicles, and will denature the keratin of hair more or less, making hair easy to yellow, brittle, easy to fall off, dull and inelastic.
Among the most harmful perms, many perms on the market contain alkaline components, which have a certain oxidation effect. Once it touches the scalp, it is easy to destroy the small skin in the hair, leading to the loss of water in the hair.
Many female friends who know a little about perm may know that perm has another great harm, that is, it will cause dry and dull hair, and hay hair is really distressed. For those with allergic skin, perm is more harmful, because the liquid medicine in perm is the most likely to produce allergic reactions. Please have an allergy test before perm to protect your hair. Avoid endangering health.
Another great harm of perm is that it will cause dry and dull hair.
Ammonium sulfonium (alkaline) in the special perm solution enters the cortex through the hair scales on the hair surface, which changes the protein chain structure of hair and forms curly hair. Generally, in perm, the small spring of cystine is disassembled with reducing chemical solution to break the sulfur-resistant bridge bond of cystine and become two cysteines. At this time, the amino acid chain of hair will be loosened and rolled into a certain waveform, which is at the mercy of others.
Then, a fixing agent is used to make the cysteine of the disconnected small spring two combination together to form a new spring and fix the hairstyle. In the process of perming, the alkaline components and oxidation in the liquid medicine will destroy the scales on the hair surface.
If the internal structure of hair is not protected, it will cause the loss of water and nutrients inside, which is harmful to hair, scalp and hair follicles, and will denature the keratin of hair more or less, making hair easy to turn yellow, brittle, dull and inelastic. Experts believe that perm should not be too frequent, not more than four times a year. Perm for pregnant women will affect the health of the fetus and should not be permed; The little girl's scalp is delicate, and it is easy to break the scalp by perm, infected with bacteria, and the scalp is dry, so it is not suitable for regular perm.
At present, mercaptoacetic acid is used as a functional component in perm agents sold at home and abroad, which also has potential safety hazards.
Four tips to help you reduce dyeing damage. Tip 1: Don't wash your hair before dyeing it.
You can wash your hair a few days before dyeing, but don't wash your hair at the moment before dyeing, because the sebaceous glands of the scalp secrete oil and form a protective film on the scalp and hair surface, which makes it less damaged by toxic chemicals in chemical hair dyes, but washing your hair will destroy this oil. Some shampoos also have the effect of sealing hair scales, which is not conducive to hair dyeing and coloring. So don't wash your hair before dyeing and perm, which not only protects your hair, but also increases the effect.
The second measure: wash your hair with vinegar after dyeing.
People's scalp is generally in a weak acidic environment, and hair can grow well in this acidic environment. However, in the process of perming and dyeing hair, the extremely irritating liquid medicine can make the scalp environment as high as PH 10 in a short time, which is undoubtedly a great harm to the hair, and even a large number of hair loss phenomena are found after perming and dyeing hair. So what should we do? You can try to add a little white vinegar to shampoo and neutralize the alkaline environment of some scalp with acetic acid, which can reduce the harm of hair dyeing and protect your hair.
The third measure: choose a reliable hairdresser and barber.
This is very important, but it is difficult for us to decide for ourselves. Perm or dye is very serious depending on two factors, one is the quality of the liquid medicine, and the other is whether the operation is excellent.
First of all, even the best potion is harmful to hair, but a good potion reduces this damage and is safer. Some unscrupulous hairdressers will use inferior potions, mainly at low prices, or even shoddy, which undoubtedly increases the harm of hair dyeing!
Secondly, operation and technology are also key. A professional hairdresser will give you a skin test before using the lotion to see if you are allergic. During the operation, the barber in charge will try not to let the medicine drip on your scalp, the coloring method and heating time are just right, and will use his professional experience to protect your hair. What about the irresponsible barber? Maybe they care more about how much you spend. You don't apply for a card, which is technically average, and even you deliberately don't do it seriously because of your cheap consumption! These human factors will hurt consumers!
So how to solve this problem? First of all, try to choose a formal and familiar hairdresser and fully communicate with the hairdresser, which is conducive to the smooth progress of the whole process. You can tell the barber yourself in advance. Allergy? 、? Not feeling well? And so on, can help hairdressers pay more attention to their work and be more careful. In short, communication is a skill. Let's sum it up!
The fourth measure: DIY perm and hair dye.
Some people have been hurt by hairdressers too many times, so they plan to dye their hair and perm themselves. I have to say that these two technologies are more and more simplified and convenient, and it is no longer difficult to do perm and dye hair at home.
Let's look at a perm first. How do we perm at home? Simple, right? Perm? And then what? A curling iron? The principle is similar, that is, according to the perm effect, the structure will be somewhat different. Perm is very simple to use. It temporarily curls hair by heating. Its advantages are high speed and no damage to hair. The disadvantage is short modeling time. Suitable for dating, gathering, emergency and other occasions.
You can also dye your hair at home, but you should dye your hair with liquid medicine. Choose some big-name hair dyes, such as gentle hair dyes such as Kao foam dyeing, Swarovski and L 'Oreal. The quality is more assured than that of a hair salon, but it is a bit troublesome to operate. Generally, brush from the root to the end of the hair, and don't touch the scalp. Kao foam dyeing is recommended, the operation is simple and the hair dye itself is mild.
In a word, perming your hair by yourself can reduce the harm of perming it for a short time, and dyeing your hair by yourself can also reduce the harm of dyeing your hair in theory, but the operation is difficult and the advantages and disadvantages should be weighed by yourself.
